We have been working on angle-resolved polarized Raman mapping of composition-gradient (1-x)Pb(Mg1/3Nb2/3)O3-xPbTiO3 (PMN-xPT) crystal to clarify the relationship between the inhomogeneous structure and the physical properties. In this talk, we report the results of our analysis of a large amount of spectral data by extracting features using multivariate curve resolution.
